This leaves us with a fairly uneven playing field: if members of the WHATWG are key decision-makers in terms of features that see immediate implementation, all proposals but theirs are at a disadvantage.

Excellent! While IÃ­m confident that the extended `srcset` syntax and the `picture` syntax can co-exist in an effort to address all of our proposed use cases ( in progress here: http://responsiveimagescg.github.com/ri-usecases/UseCases.html ), the current `picture` extension specification aims to make the use of that resolution-switching aspect Ã³ we believe itÃ­s the right tool for the job.
Would it be alright if I contacted you off-list about this? We have a prototype `picture` implementation underway and IÃ­d love to coordinate our efforts, or just compare notes!

I can only hope that changes as our extension specification continues to shape up. WeÃ­ve isolated and addressed a number of issues ( https://github.com/Wilto/draft-prop/issues?state=closed ) as a result of ongoing discussion and our prototyping, and weÃ­re always looking for feedback from vendors, formal or informal.
ItÃ­s a problem long overdue for a solution, regardless of the final form that solution takes. IÃ­d love to work more closely with the WebKit team in an effort to find one.
